Application filed December 27,1904. Serial No. 238,552-

To all whom, it may concern:

Be it known that I, HEINRICHVOGT, manufacturer, a subject of the German Emperor, residing at Leopoldshohe, Germany, have invented an Improved Machine for Making Igniting-Blocks, of which the following is a specification.

My invention relates to the production of an elevation of the product as formed by my Fig. 6 is a view in ele-- improved machine. vation of the finished product.

Like characters of reference designate similar parts throughout the different figures of the drawings.

Referring now in detail to the drawings, there is shown a machine consisting of a base or frame A, carrying a stationary supportingdisk (1. Upon the disk (1, is rotatably mounted a second disk I), the said disks being grooved on their adjacent faces to form a ball-race for antifriction-balls b.

, the latter from being thrust out of operative alinement with the disk a. Rotative movement is imparted to the disk I) by means of a shaft m, which projects downwardly through the disk a and carries on its lower end a beveled gear 8. A second gear 1", meshing with the gear 3, is carried by a shaft 1", the latter being belted to a pulley Z, which is given an intermittent rotary movement.

The disk I) is provided with a plurality of radial slots d, having inwardly-projecting lugs b In each of said slots there is seated a. mold-bar f, desirably coextensive in length with the slot and adapted to rest upon the projecting lugs b Said bars f are relatively narrow in depth and when seated upon the lugs I) leave a considerable vacant space with- An annular flange 6 secured to the disk a, projects upwardly about the periphery thereof to a point slightly above the disk I), preventingin the molding slot or cavity. Each of said bars f are provided, on their upper margins I with a plurality of V-shaped recesses extending throughout the lengthof each bar and forming a plurality of projecting teeth f.

A supporting-plate y, carrying a suitable stamping mechanism and a forming or compressing surface, as shown, is mounted near its outer end upon the flange b and is clamped in place thereon by bolts 'y, which project up through the plate y and which carry threaded hand-wheels y, constituting tighteningnuts; The plate 2 is securedat its opposite end to the plate I) upon a threaded stud g which projects upwardly through the plate y and is provided with a threaded handwheel W. In practice the hand-wheel y will not be turned down to impinge tightly upon the plate y, inasmuch as the threaded stud y serves the purpose of centering the plate y to bring the stamping mechanism in lateral alinement with the slots d. Said stamping mechanism consists of vertically disposed parallel guides g, desirably formed integral with the plate y. A stamping-block his provided to reciprocate between said guides, which consists of a body portion 72/ and'one or more downwardly-projecting plates 1). The stamping-block h is reciprocated by means of a cam n and rod 0, as shownin Fig. 1. The cam n is provided with a plurality of irregular portions 00, which serve to raise the rod 0 and the knife-block h (the latter falling by gravity) rapidly while one of the slots at is V The cam is in register with the stamper. also provided with a concentric portion or, which engages the rod 0 and holds-the same in an elevated position while the disk I) is ro tating to bring a succeeding slot into register with the stamper. The cam will be driven at a relatively high rate of speed, so thatthe stamper will complete a number of reciprocations while one of the slots 01 is in register with the stamper, resulting in effectually packing the material in place. The cam n is mounted on a gear n, Fig. 1, which is driven by a pinion n When the machine is designed for foot-power, as shown, the shaft .on which the pinion n? is mounted carries a balance-wheel n which is connected by crankarms a z and a link .2 with a manually-operating shaft .2 Said shaft, as shown in Fig. 1, is provided with a foot-lever z The plate y'is provided with a downwardly-projecting forming portion if, which is spaced 1 its ends together, as shown in Fig. 6, forming apart from the Stamper a sufficient distance to register with the next succeeding slot d.

In vertical alinement with the projection 1 there is formed slots in the disks a and l), in which a compressor-block i reciprocates.

to with a weight 1c. The block i is adapted for engagement with the lower surface of the mold-bars f and recedes from the position shown in Fig. 4 downwardly during rotation of the disk I).

The plate a is provided with ejecting-rails c and 0 which desirably extend from a point adjacent the compressor-block i to a point opposite the same, the said rails being inclined upwardly from the compressor-block and terminating abruptly at their highest ends. Said rails occupy grooves formed in the disk I) and project within the slots (Z during the operation of the disk 6.

In the operation of forming a coal-igniter the material is loosely packed by hand or otherwise into slots which occupy positions between the ends of the ejector-rails and the stamping mechanism, the forming-bars in these slots resting upon the lugs 6 leaving the normal depth and length of the slots open to receive the material. As the disk Z) rotates and the filled slots (1 are successively brought into alinement with the stamper the material is packed tightly in place by the rapidly-reciprocating plates 1). After the material has been packed and the disk is rotated the slots will be brought into alinement with the compressor-block i, which will engage the barf, as shown in Fig. 4, forcing the same upwardly against the forming-projection y to compress the block and secure a smooth upper surface therefor. During this compression it will be understood that the stamping-knives 2) will be packing the material into the next rearmost slot, the two operations being carried on simultaneously. It will be understood that the compression by means of the block'i may be manually effected by the operator should the weight 7c prove ineffective. The igniter, as shown in Fig. 4, is now finished, and as the disk I) rotates the bar f will engage the ejector-rails c and raising the bar and product to the position shown at the right of Fig. 4, whereupon the igniter may be removed by hand or by other means. When rotation of the disk 6 is continued, the bar f, as shown at the right of Fig. 4, riding over the abrupt ends of the rails c and 0 will quickly drop to the bottom of the slot (1 into engagement with lugs b whereupon it will be ready for the reception of new material. When the igniter is removed from the machine, it consists of a straight smooth bar of tightly-packed material, as shown in Fig. 5, which is provided on one side with a plurality of V-shaped recesses. The bar in this form is bent to bring a circular block provided with a relatively small central opening and a plurality of radial slots, one of which extends to the outer periphery. While it is not essential that the bar should be bent in the form Said block 1' is connected by a link 1; and lever shown in Fig. 6, it is obvious that this form presents many advantages over the others, inasmuch as it is a compact body easy to handle and ship. Furthermore, it is provided near and around its center with open spaces, thereby effectively promoting combustion.

I prefer to operate upon the material when the same is hot, as it is then more easily packed and molded in the'machine and can be more readily formed into a finished product after it is discharged from the machine.

The device of my invention may be used for making igniters of any kind. of material capable of being molded into prescribed forms. It will be understood, however, that material must first be treated with a binding agent, so that it will adhere and remain intact after being formed into the finished product.

Processes and methods of treating pulverized coal, peat, or other volatile materials for fuel purposes with binding agents are well known and constitute no feature of the present invention, and therefore will not be herein more fully described.
